WHY BUY USED DN SOLUTIONS PUMA ST 20GS II
Purchasing a used DN Solutions PUMA ST 20GS II allows manufacturers to acquire advanced twin-spindle machining capability while avoiding the significant capital investment associated with new equipment. The machine is specifically designed to improve production efficiency through complete machining capability, allowing manufacturers to process parts from raw stock to finished component without requiring secondary operations.
One of the most significant benefits of the ST 20GS II is its automatic workpiece transfer system. After front-side machining is completed in the main spindle, the part is automatically transferred to the sub-spindle where back-side machining operations are performed. This eliminates manual intervention, reduces setup time, and dramatically improves overall throughput. For manufacturers producing thousands of parts per month, these productivity gains can generate substantial cost savings.
The machine’s twin-spindle configuration also improves dimensional consistency. Because the part remains within the machine throughout the machining cycle, there is less opportunity for handling errors or setup variation. This contributes to improved quality control and greater repeatability, especially in industries where precision is critical.
Another advantage is the machine’s compact footprint relative to its production capability. Manufacturers can achieve high production output without dedicating excessive floor space to multiple machines. This makes the PUMA ST 20GS II especially attractive for facilities seeking to maximize productivity within limited manufacturing space.
The machine’s proven reliability further enhances its value. DN Solutions has established a strong reputation for building durable machine tools capable of operating continuously in demanding production environments. Properly maintained PUMA ST machines often remain productive for many years while requiring minimal downtime.
For manufacturers seeking higher productivity, reduced labor costs, and improved manufacturing efficiency, a used PUMA ST 20GS II represents an excellent investment that continues to deliver strong returns throughout its operational life.
HOW MUCH DOES A USED DN SOLUTIONS PUMA ST 20GS II COST?
The cost of a used DN Solutions PUMA ST 20GS II can vary significantly depending on machine age, operating hours, overall condition, maintenance history, tooling packages, and installed automation options. Because the machine incorporates twin-spindle technology and complete machining capability, it typically commands stronger resale values than conventional single-spindle CNC turning centers.
Most used PUMA ST 20GS II machines typically sell within a range of approximately $75,000 to $250,000. Older machines with higher spindle hours generally occupy the lower portion of the pricing range, while newer machines equipped with automation systems, low operating hours, and extensive tooling packages can achieve premium market values.
Machine condition is one of the most important pricing factors. Buyers frequently inspect spindle performance, turret indexing accuracy, sub-spindle functionality, hydraulic systems, lubrication systems, machine geometry, and maintenance records. Machines that have been properly maintained generally command higher resale values due to reduced risk and expected reliability.
Additional equipment can significantly influence pricing. Features such as bar feeders, robotic loading systems, parts catchers, chip conveyors, high-pressure coolant systems, tool presetters, and tooling packages can add considerable value. For many buyers, acquiring a machine with these accessories already installed reduces future capital expenditures and shortens implementation time.
Market demand also affects pricing. Industries such as automotive manufacturing, hydraulic component production, aerospace machining, and medical manufacturing frequently seek twin-spindle machines capable of complete part processing. Strong demand from these sectors helps maintain healthy resale values for quality used machines.
Although transportation, rigging, and installation costs should be considered during budgeting, purchasing a used PUMA ST 20GS II remains a highly cost-effective alternative to purchasing a new twin-spindle turning center. Manufacturers often achieve substantial savings while gaining access to advanced automation and productivity-enhancing technology.
